'jo a li 'u'howt it may concern:

lie it kimu'nthat l, HENRY DOIJIER. .112, a citizen of th United States, residing at Philadelphia, county of Philadel 'ihia, and Stateof Pennsylvania, have invented certain new and useful Improvement-sin Incandescent-l lamp Shades, of which the following is a specification. I

My invention resides in a shade or reflector particularly adaptable to use with incandescent lamps.

1t is the object of my invention to provide a shade or reflector and holder; which ,shall be of the utmost simplicity, without. lacking durability and efliciency. To this end I providea sheet metal shade or reflector memthereto, such fingers extending inwardly and outwardly in the case where the-holder-portion of the reflector or shade is applied to a portion of the shade or reflector which is at a considerable angle with the axis of the lamp socket.

For an illustration of two of the many forms my invention may take reference is to be had to the accom- 'panying drawing, in which: p i

Figure 1 is a vertical section through the shade or reflector member, the .lamp, socket and holder fingers being shown in elevation. Fig. 2 shows a .portion of the surface of the shade orreflector member after having been operatediupon by a die to form the blanks for the holder fingers. Fig. 3 is a vertical sectional ,view of the shade or reflector member in which the'inwardly and outwardly extending fingers are formed'out of a separate sheet of metal which is secured to the shade or reflector member.

Referring to the drawing, R represents a shade or reflector, preferablyoi sheet steel, brass, aluminium, or

other suitable material, and is in the form of a surface of revolution whose axis is the vertical one XXL An incandescent lamp L is secured in the usual manner in thelamp socket S having the usual switch key K and.

the usual beadB. v x

- F, F are fingers or finger members having the beads b, b to engage over the socket bead B to hold the shade or reflector member R upon the socket. As shown in Fig. 1 these'fingers are integral with. the shade or reflector member It, being formed out of the material in the region where the perforation is to be made to receive the lamp socket S. I

In Fig. 2 is shown a portion of the surface of there- Y flector member lt after it has been operated upon by a .die to stamp out the finger members F. The general outer outline is elliptical so that when the fingers F are bent outwardly and inwardly, as shown in Fig. 1, the circular socket S may extend into the aperture, which is elliptical, due tothe slant of the reflector R with re- I spect to the axis of the socket S.

l By the arrangement shown in Fig. 1, the lamp socket is very easily introduced into the aperture. of the shade or reflector. Furthermore, the lamp L is brought into a more central position with respect to the axis of the surface X-X than has heretofore been possible, especially with shades or reflectors having neck portions or extending portions carrying the holder fingers. It is seen in Fig. 1 that the socket head 13. is partly inside of the shade and partly outside of the shade, due to the slant of the reflector R, in the region of the aperture. This construction is of the utmost simplicity and renders cost of manufacture extremely low.

In Fig. 3 the reflector member R has formed in it anelliptical opening E, and secured around the inner edge of such opening is the sheet G in which have been stamped and formed the fingers F by a process'sirnilar to that illustrated in Fig. 2. The member G, having the fingers F integral therewith, may be soldered, riveted, or otherwise secured either to the inside or outside ofthe shade or reflector member R; then the fingers are bent inwardly and outwardly as in the case of Fig. 1. Here .again, as in Fig. 1 the socket bead or the engaging portion of the socket is bothinside and outside of the reflector, but the bending outwardly and inwardly of sets i I IS 1 l bringing the lamp in the most desirable position withrespect tothe inner reflector surface of the member It.

While I have here shown the lamp socket axis at right angles to the axis of revolution of the shade or reflector member B, it is to be understood that the invention is applicable to other angles and particularly where t e side of the shade member has a substantial slopewitli respect to the'lamp socket.

.. What I claim is:

1'. As an article of manufacture/a shade or reflector having inwardly and outwardly extending socket engaging members disposed about an aperture in a slanting wall and adapted toengage a socket at points all substantially equally distant along the socket axis.

2. in combination, a shade or reflector member having inwardly and outwardly extending supporting members, a support disposed at an angle to the shade or reflector wall, allof said inwardly and outwardly extending supporting members adapted to register with the same part ofsaidsupport. p

3. In combination, a shade or reflector'wallQ-an aper-v ture therein, a lampsocketextending into-said aperture and having its axis at-an angle with said wall, and inwardly and outwardly extending socket engaging members disposed about said aperture and engaging the same socket "part.

4. In combination,.asl1ade or reflector wall, an aperture therein, a socket extending into said aperture and having its axis at an angle with said wall, a bead upon said socket and beaded inwardly and gutwardly extending members disposed about said apertiire and engaging said socketbead. v I;

5. in combination, a shade or reflector wall, an aperture therein, a socket. extending into said nper-ture'andhaving its axis at an angle with said wall, a bend on of fingers locates the socket in the :best position foi 80 a shade or reflector member an aperture in a slanting 10 wall thereof, and socket engaging members disposed about said aperture and adapted to engage the same socket part.

In testimony whereof I have hereunto aflixed my signature in the presence of the t Witnesses DANL. WEBSTER, Jr., ANNA E. STEINBOCK.
